STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

MCA0438Biopolymer transport protein, ExbD/TolR family; Identified by similarity to SP:Q05606; match to protein family HMM PF02472. (137 aa)    
Predicted Functional Partners:
exbB2
MotA/TolQ/ExbB proton channel family domain protein; Identified by match to protein family HMM PF01618.
 
 
 0.975
MCA0436
MotA/TolQ/ExbB proton channel family protein; Identified by match to protein family HMM PF01618.
 
 
 0.966
MCA0435
Conserved hypothetical protein; Identified by similarity to OMNI:VC1548.
 
     0.927
MCA0439
TonB domain protein; Interacts with outer membrane receptor proteins that carry out high-affinity binding and energy dependent uptake into the periplasmic space of specific substrates. It could act to transduce energy from the cytoplasmic membrane to specific energy-requiring processes in the outer membrane, resulting in the release into the periplasm of ligands bound by these outer membrane proteins. Belongs to the TonB family.
